Research equipment requested is going to be used in analysis of nutrients - nitrogen and phosphorus in water and wastewater.  Currently nutrient removal is the biggest issue on the environmental agenda in Manitoba.  The Applicant chairs the International Water Association's specialist group on Nutrient Removal and Recovery and has seen the nutrient problem (over-fertilization of lakes and streams also called eutrophication) becoming number one priority around the world.  The Applicants have been engaged in biological nutrient removal for the last two decades using a 30 years old colorimetric auto-analyzer, which although continuously refurbished and upgraded, has reached the limit of its functional life and cannot provide quality required nor process the numbers of samples that are analyzed in the environmental engineering laboratories.   The Civil Engineering and Biosystems Engineering students share the laboratories (the environmental laboratories are contiguous) and all need the new equipment to conduct research for example on: nitrification (ammonia oxidation) in cold temperatures (Mr Hwang) and after anoxic stress (Ms Wong); total nitrogen removal after ozone treatment of the biomass (Ms Dytczak); nitrogen removal in biofilm reactors (Ms Celmer); autotrophic denitrification (Ms Celmer, Mr Hwang, Dr Rezania); use of industrial waste or generation of carbon for denitrification (Mr Chen); macrophyte harvesting to prevent nutrient recycle in the Red River delta (Mr Grosshank); nutrient removal in granular activated sludge reactors (Ms Zhou); anaerobic ammonia removal (Mr Jaroszynski); manure treatment in membrane bioreactors (Mr Yang).   Our work has economic benefits.  Winnipeg alone is facing over $1 B potential expenditures on wastewater infrastructure and upgrades to its three plants.  Any improvements in the nutrient removal process and associated solids management will be translated to lower burden to the Canadian taxpayer.

所要求的研究设备将用于分析营养物质 - 水和废水中的氮和磷。目前，清除营养是曼尼托巴省环境议程的最大问题。该应用程序主持国际水协会的营养清除和恢复专家小组，并看到了养分问题（湖泊和流的过度利用也称为富营养化）成为全球第一名。在过去的二十年中，申请人使用了30年历史的比色法自动分析仪从事生物营养的去除，这些自动分析仪仍在不断进行翻新和升级，已达到其功能寿命的极限，无法提供所需的质量，也无法处理在环境工程实验室中分析的样品数量。土木工程和生物系统工程专业的学生共享实验室（环境实验室连续），并且所有人都需要新设备来进行研究：降温温度（Mr Mr）和缺氧压力后的硝化（氨氧化）（氨氧化）（MS Wong）；臭氧处理生物质后的总氮去除（MS Dytczak）；生物膜反应器中的氮去除（MS Celmer）；自养分子化（Celmer女士，Hwang先生，Rezania博士）；使用工业废物或生成碳替代化（Chen先生）；大植物收获以防止红河三角洲的养分回收（Mr Grosshank）；颗粒活性污泥反应堆中的营养去除（MS Zhou）；去除厌氧氨（Jaroszynski先生）；膜生物反应器中的手动处理（先生）。我们的工作有经济利益。仅温尼伯就面临着超过1美元的废水基础设施的潜在支出，并升级到其三种工厂。营养清除过程和相关固体管理的任何改进都将转化为将加拿大纳税人降低。
